Show the structure of ⓐ the three-carbon alcohol with an —OH group at the end of the chain. ⓑ the three-carbon carboxylic acid. ⓒ the ester formed when these two compounds react.

Question

Show the structure of

ⓐ the three-carbon alcohol with an —OH group at the end of the chain.

ⓑ the three-carbon carboxylic acid.

ⓐ AND ⓑ

STRATEGY

1. Write the parent compound chain.
2. Put the functional group in the specified position.
3. Fill in the structural formula with H atoms.

Accepted Answer

ⓐ AND ⓑ

C-C-C

C-C-C-OH

[latex]CH_{3}-CH_{2}-CH_{2}-OH [/latex]

(a) 1. Parent compound chain

2. Functional group

3. Hydrogen atoms

C-C-C

[latex]C-C-\underset{\overset{||}{O} }{C} -OH[/latex]

[latex]CH_{3}CH_{2}-\underset{\overset{||}{O} }{C}-OH [/latex]

(b) 1. Parent compound chain

2. Functional group

3. Hydrogen atoms

ⓒ

Join the acid and the alcohol and remove OH from the functional group (COOH) of the acid and the H from the functional group (OH) of the alcohol.

[latex]CH_{3}CH_{2}CH_{2}-\xcancel{OH}[/latex] [latex]\xcancel{HO}-\underset{\overset{||}{O} }{C}-CH_{2}CH_{3}[/latex]

↓

[latex]CH_{3}CH_{2}CH_{2}-O-\underset{\overset{||}{O} }{C}-CH_{2}CH_{3}[/latex]
